Oh, hey...if we're going to Henry VI, VII, VIII, Edward IV(?), and Richard III, I've got to recommend Philippa Gregory's Cousin's Wars series - The Lady of the Rivers, The White Queen, The Red Queen, The Kingmaker's Daughter, The White Princess, The King's Curse.
I can't say it made me understand the Wars of the Roses, but it showed me why I never will understand it - every family has Henrys, Edwards, Richards, Elizabeths, and Margarets so it's effing impossible to understand! :-)
Gregory has also convinced me that Shakespeare screwed Richard III's memory to avoid attracting punishment or to win favor from Elizabeth Tudor.
